SPECIFICATION forming part of Letters Patent No. 736,542, dated August 18, 1903.

Application filed July 18, 1902. Serial No. 116,019. (No model.)

To all whom it may concern:

Be it known that I, GUSTAV B. PETSCHE, a subject of the Emperor of Germany, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Governors, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to governors for steamengines, and has for its object to provide for a construction whereby the governor can be readily detached from its actuating mechanism and whereby also the valve controlled by the governor can be adjusted and set to any desired permanent position.

With these objects in View my invention consists in constructing a governor with a rotatable and longitudinally-movable spindle, which in normal position is actuated by a moving part of the engine, and providing means for shifting the spindle longitudinally to disconnect it from the operative mechanism and also through the motion of the spindle to adjust and set the controlled valve upon which the governor normally operates.

The nature of my improvements will be best understood as described in connection with the drawings, in which they are illustrated, and in which Figure 1 is a side elevation of the governor embodying my improvements. Fig. 2 is a plan View thereof; and Fig. 3, a side elevation of another modified construction,also embodying my improvements.

In the construction shown in Figs 1 and 2 the governor is supported on a base Q, having a laterally-extending platform Q and arch-like arms Q springing from the ends of this platform and supporting the bearing Q in which the spindle turns. L indicates the spindle, vertically supported in the bearing Q and having at its lower end a friction-disk L, which normally rests in contact with a friction-wheel N, keyed to a shaft N, which has also secured to it a pulley N about which passes a belt N operated by some moving part of the engine. (Not shown.) The friction-wheel N is free to move longitution.

dinally on the shaft N and is adjusted to position by means of the arm R attached to itsl hub and having a threaded perforation through which it screws to the rod R, actuated by a hand-wheel R and supported by arms R R L indicates the usual Weights, pivoted to the spindle L and connected to a sleeve L which slides upon the shaft and has attached to it a collar L through which motion is communicated to the bell-crank lever M and to the connecting-rod M, which in turn communicates with the valve controlled by the governor, but not shown in the drawings. Z indicates a collar secured to the spindle L and uponwhich the sleeve L can rest when the governor is not in normal opera- 1 indicates another collar secured to the spindle L and lying withih a threaded thimble p, which is secured to the lower part of the bearing Q and in which screws the perforated adj listing-screw 0, having a handwheel 0'.

In the modification shown in Fig. 3 the longitudinally-adj ustable spindle has its frictiondisk L secured to its top and resting on a friction-wheel N, driven from the engine, as in the first-described apparatus. The spindle turns and is longitudinally movable in bearings S and S and is longitudinally adjusted by means of an adjusting-screw 0, working in a threaded bearing S and actuated by a hand-wheel O. In other respects the devices are practically alike and are essentially alike in their mode of operation.

In operation the adjusting-screw O is retracted, so that it does not support the spindle L, the weight of which is supported through the friction-disk L upon the friction-wheel N, and the governor operates in the usual manner, the speed of rotation of the spindle regulating the rise and fall of the weights L which through the sleeve and collar L L act upon the controlling-valve. When itis desired to disconnect the governor from the operative mechanism, the screw 0 is turned up, so as to engage and lift the spindle, thereby carrying the friction-disk out of contact-with the friction-wheel and throwing the governor out of operative connection. The setting of the controlled valve is efiected by the simple ex pedient of still further screwing up the screws 0, the lifting of the spindle being communicated through the collars l or any other con-v venient device or connection to the sleeve L and through it communicated to the valve, as'in the case of normal operation.

It Will be understood that, save where expressly so limited in the claims, my invention is not limited to the use of friction devices for giving motion to the spindle, for any detachable connection disengaged by lifting the spindle will serve the same purpose.

Having now described my invention, what I-claim as new, and desire to secure by Letters Patent, is

1. Asteam-engine governor,-havingin combination, a spindle, rotatable and longitudinally movable in its bearings, means for driv ing the spindle, operative when the spindle is in normal position, weights secured. to the spindle and operated by it, a sleeve connected to said weights and coupled to operate a regulating-valve, and means for shifting the spindie and sleeve longitudinally to disconnect the governor from the actuating mechanism and to adjust the sleeve and its valve connections to a'determined position.

2. Asteam-engine governor, havingin combination, a rotatable and longitudinally-mow able spindle, a friction-wheel driven by the engine, a friction-disk secured to the spindle and adapted to be supported on and driven by the friction-wheel, weights secured to and driven by the spindle, a longitudinally-mow able sleeve connected to the weights and sliding on the spindle, valve connections actuated by said sleeve, and means for raising the spindle and, through it, the sleeve, to lift the friction-disk out of operative position on the friction-wheel, and to adjust the valve connection when the governoris out of operation.
